What is Cinetrii?
Cinetrii is a service aimed at film enthusiasts who want to understand the context of the films that they love. Directors and screenwriters might take inspiration from works that have come before - Cinetrii tries to trace this lineage. The algorithm analyzes written reviews by film critics, seeks out references to other works and tries to rank the connections on relevance.
Rationale
Critics have a tendency to infer possible inspirations to a film. They will reference other works, namedrop directors, compare and contrast. Using large-scale text analysis it is possible to crowdsource knowledge from lifetimes of cinematic experience and art appreciation, while also giving credit to the reviewers.Interface

On mobile, the interface is a basic scrolling page, with the strongest connection appearing first.
Cinetrii for film recommendations


When the art form is reduced to vector calculus, these are the kind of obtuse results that emerge. They're not bad - the films suggested are good, but there is little in terms of explanation as to why they're there. Traditional recommendation systems, predictive models that are trained on user ratings data and the like, lack interpretability. There is also often a strong gravitational pull towards mainstream, popular titles which few people haven't seen, let alone need a system to discover them.
So how does Cinetrii do?


Cinetrii can provide suggestions with similar themes, characterizations or visual styles and motifs. It's all dependent on the type of film and the discussion that surrounds it. Some films, like big hollywood blockbusters, prompt few critics to draw comparisons to other works (beside other entries in the franchise, e.g. Marvel) and so the algorithm may not perform as well. However, when a connection is made you can review the quotes that determined the connection. The connections are interpretable.
Cinetrii does not weight results toward mainstream choices, rather a connection is boosted by the number of critics making the same reference. It's likely that Cinetrii can suggest something that's new to you. You may have seen Drive and Birdman, but have you seen Ace in the Hole?
Cinetrii is a hobby project.
